A new binder system for
castables containing fume silica

Secar Xeniom is a newly engineered binder
system designed by Kerneos for a wide range
of low cement castables.
Secar Xeniom addresses the demand for high
performance monolithics, which are nowadays
required for key applications globally and
where the route to formulate high performance
castables becomes complicated.
Secar Xeniom aims to address these issues
by offering multiple benefits based around
reliability, user-friendliness, robustness and
performance.
THANKS TO SECAR XENIOM, FORMULATORS
WILL BE ABLE TO:
manage more easily the complex variations of
raw materials and their impact on flow,
working time and hardening,
put more robustness into mixes produced,
address raw material sourcing more efficiently
with fewer components in the formulation
and a broader choice of local raw materials,
engage in a technical collaboration with the
global network of Kerneos,
deliver higher performance to ULCC and LCC
fume silica castable systems.

As a mineral buffer, Secar Xeniom greatly
facilitates the placing of castables allowing the
creation of more stable systems that are less
sensitive to fume silica lot variation. At the same
time, other properties like setting time and
hardening remain consistent.
Secar Xeniom based systems demonstrate
more robustness towards changes in ambient
temperature. This property enables to manage
smoothly the seasonal transitions common in
many regions (5 to 35°C).

Second, SIMPLICITY
Secar Xeniom is a sophisticated formulation
engine with one goal: to make development
work easier!
Secar Xeniom behaves well with traditional
admixtures and can simplify many formulations,
often requiring the use of fewer admixtures. It is
well known that low dosage can be challenging
to control effectively during production or on
job site. Secar Xeniom is particularly suited to
reduce such requirements.
Secar Xeniom is designed to exploit a single
retarder logic, allowing the creation of systems
convenient to adjust when the temperature
varies. This is a significant improvement
compared to the duo retarder / accelerator
approach frequently used, which can be
awkward to deal with.
Secar Xeniom reaches a proper flowability
with low water addition and has been tested
successfully with several kinds of mixers.
Secar Xeniom is, however, forgiving if excess
of water is added and will tend to keep a similar
level of performance in such circumstances.

Third, IMPROVED
PERFORMANCE
Despite the focus on application and
formulation ease, Secar Xeniom systems still
meet the needs of the most demanding ULCC
and LCC dense castables.
In term of green properties, Secar Xeniom
shows good working time and rapid structure
development, synonymous with high initial
strength.
In term of high temperature properties,
Secar Xeniom provides “best in class” hot
mechanical strengths and abrasion resistance.
Refractoriness under load is also better than
traditional systems and improved permanent
linear change is another feature of the product.
Secar Xeniom will give its best performance
when new castables are designed from first
principals and not when the product is just used to
replace one product by the new product. A close
cooperation with Kerneos is advised allowing
access to the wide range of development testing
conducted with many widely available raw
materials that have been studied during the
development of Secar Xeniom.
For many years, the Secar ® range has been
Kerneos’ commitment to quality stability, and
wide availability supported by a high level
dialogue allowing customers to meet their enduser
requirements. Secar Xeniom inherits
these qualities and goes one step further by
offering a system aimed to efficiently work inside
customer’s R&D process and should allow
the development of high performance castables
quickly.
